Stack all modules and then connect the ethernet cable, as follows:

==Program==
Download the program:
https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_ENC/ENCnetworkone

==Debug==

Step 1：Download the EtherCard library and copy to your libraries fold of IDE, then restart IDE.
https://github.com/jcw/ethercard

Step 2：Before connect to network, you need learn some network parameter.

'''Network parameter：'''
Before connecting Ethernet shield to the net, you need some parameters:

*MAC address, is a 48bit number that univocally identify each device in the net. Every company that produces network devices owns a code (OUI) that rappresents the address’ first 24bits;
*IP address, is a 32bit number (IPv4) that identify the device in the local network;
*Subnet mask is a 32bit number that allows devices to know if another device belongs to the same local network;
*(usually) gateway is the IP address assigned to a device (router…) that allows to reach devices in different networks.

You need to choose a MAC address not alredy used in your network… in the examples we usually choose MAC addresses with a not already assigned organization code (es. DD-DD-DD).

IP parameters (address, subnet, gateway) have to be consistent with the ones configured to other devices in your local network: an unique IP address and the same subnet mask and gateway.

Sometimes a DHCP server is available, that automatically configures new devices in the network: in a next example I’m going to show how to use this with Arduino.

Step 3：Explain the program.

//First you need to include the EtherCard library and define some variables: MAC address, IP address and a buffer the library will use to store incoming and outgoing data;

include <EtherCard.h>
static byte mymac[] = {0x74,0x69,0x69,0x2D,0x30,0x31};
static byte myip[] = {192,168,1,10};
byte Ethernet::buffer[700];

ether.staticSetup(myip);
//complete configuration with a static configuration for the IP address. Use the function staticSetup() method to configure the static IP, it has three parameters, that are ip address, gateway and DNS.
IP is mandatory, others are optional. The following is the defination.

static bool staticSetup (const uint8_t* my_ip =0, const uint8_t* gw_ip =0, const uint8_t* dns_ip =0);

//in the loop, you need only 2 instructions:

//packetReceive()method receives a new incoming packet from the network;

//packetLoop() method answers to specific incoming messages, including the “ping” ones (ICMP echo request)

ether.packetLoop(ether.packetReceive());

Step 4：Download the program and compile it.

Step 5：ping！

Check a device if has online, the "ping" command is a simple method. Ping the destination device's IP.

The upper picture indicates that the device has obeen online.
